Please read the following notes before using the datasheets:. Over-current-proof Customer must apply resistors for protection, otherwise slight voltage shift will cause big current change (Burn out will happen).. Storage. If the package contains a moisture proof bag inside, please don't open the package before using.. Before opening the package, the LEDs should be kept at or less and 8%RH or less.. The LEDs should be used within a year.. After opening the package, the LEDs should be kept at or less and %RH or less.. Soldering Iron Each terminal is to go to the tip of soldering iron temperature less than for seconds within once in less than the soldering iron capacity W. Leave two seconds and more intervals, and do soldering of each terminal. Be careful because the damage of the product is often started at the time of the hand solder.. Soldering When soldering, for Lamp without stopper type and must be leave a minimum of mm clearance from the base of the lens to the soldering point. To avoided the Epoxy climb up on lead frame and was impact to non-soldering problem, dipping the lens into the solder must be avoided. Do not apply any external stress to the lead frame during soldering while the LED is at high temperature. Recommended soldering conditions: Temperature Soldering Time Soldering Iron Max. sec.max. (one time only) Pre-heat Pre-heat Time Solder Wave Soldering Time Wave Soldering Max. sec. Max. Max. sec.max. Note: Excessive soldering temperature and / or time might result in deformation of the LED lens or catastrophic failure of the LED.. Repairing Repair should not be done after the LEDs have been soldered. When repairing is unavoidable, a double-head soldering iron should be used. It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.. Caution in ESD Static Electricity and surge damages the LED. It is recommended to use a wrist band or anti-electrostatic glove when handling the LED. All devices equipment and machinery must be properly grounded. Spec No: W88C/D Rev No: V. Date: Sep// Page: OF
